Since the board was made of stainless steel with the reconstruction of the control panel, I used this in a similar atmosphere, but because I reflect light, I felt a little difficult to see the letters. Yellow or orange tape may have been better in terms of practicality.

Although it is not "OO asked", I tried using it as if it would be the year when it glows like "gold" like the glow of this gold. Apart from whether this year shined or not, the brightness in the bookshelf is the best. The difference with other colors you can see at a glance is recommended. Now I'm thinking about using 'silver color'.
